Abstract

Here we present a novel method for fabricating large, ordered arrays of 3D nanocups for
plasmonic applications. Previously, it has been demonstrated that nanocups provide a unique method for
bending scattered light by creating “magnetic plasmon” responses in optical frequencies. However,
creating large, ordered arrays of nanocups has remained a significant challenge. We constructed a
large (0.5 cm X 1.0 cm), ordered array of nanocups via nanoimprint lithography (NIL), soft
lithography, and shadow evaporation. This methodology enables high control over the shapes and optical
properties of asymmetric nanocups, and may facilitates the applications of nanocups in superlenses,
optical nanocircuits, and cloaking devices.
